Hello,

Is there a way to specify custom alignment for structures and variables, 
something like __declspec(align(<alignment>)) ?

Thanks.

As far as I understood the documentation this pragma sets alignment for 
members only, but not instances of that struct or class. For example, 
how would I declare an int variable, which would appear at 128 byte 
aligned address ?

Thanks.

There's currently no way to do it statically, as segments themselves are 
aligned on 16 byte boundaries. You could do it dynamically by allocating 
a chunk of memory and picking a 128 byte aligned piece of it.

Just for a better grasp on the issue: why is there any need to "fix" 
such a thing?

IMNHO this is not a fault or defect of the compiler, or is it?

Well, yes, sorry for putting it wrong,

Anyway,

Is this feature going to be implemented any time soon ?

Thanks.
